The aerospace industry is undergoing a revolution with the large-scale
development of eVTOL (Electric Vertical Take-Off & Landing) and MEA (More
Electric Aircraft). These aerial vehicles, many of them unmanned vehicles (UAV),
will serve a variety of service-related functions: Search and Rescue (SAR),
Medivac, delivery and lift operations, aerial mapping, and, of course, human
transportation [1].
Despite its numerous functionalities, this type of vehicle has a serious problem,
which is its usual batteries, the main means for its operation. Due to its
autonomy not being so effective compared to its charging time, generating a
considerable loss of time. In this context, it is necessary to find forms of
components that can replace these batteries, so that the effective development
of these vehicles is possible.
Studies done in other means of transportation point out that the use of hydrogen
fuel cells has grown a lot. In this way, it is known that this type of fuel is
seen as something of the future, but many companies have evaluated the
possibility of implementation in cars, trains, and even airplanes. Therefore, a
literature review will be presented about this new type of technology,
demonstrating its advantages and its use. Finally, after careful analysis of the
issues highlighted throughout the article, the best effective solution for
replacing the batteries will be presented, a component that has caused major
problems for the developers of this new aircraft [28].
